SPECIFICATION forming part of Letters Patent No. 467,017, dated January12, 1892.

Application filed April 15, 1891. Serial No. 388,960. (No model.) I

To all whom, it may concern:

Be it known that I, CARL OLSEN, of Long Island City, in the county ofQueens and State of New York, have invented a new and ImprovedInvalid-Bed, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in invalid-beds; and the object ofmy invention is to produce a bed which is especially adapted for use inthe sick-room and which may be used as an ordinary bed. I

To this end my invention consists in certain features of constructionand combinations of parts which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a broken plan view of a bed embodying my invention, aportion of the spring being broken away to show the operative parts.Fig. 2 is a side elevation of the bed. Fig. 3 is a cross-section on theline 3 3 in Fig. 1, showing the commode raised into the central openingin the spring. Fig. 4 is a similar view, but with the commode lowered.Fig. 5 is a broken enlarged detail View of the Fig. 6 is a brokenenlarged detail View of the commode and its support, showing also themeans of tilting it. Fig. 7 is a broken sectional plan on the line 7 7in Fig. 8, showing one corner of the bedstead and the manner in whichthe parts are secured together. Fig. 8 is a broken detail View, partlyin section, of one of the corners of the bedstead. Fig. 9 is a brokendetail View of the central hanger beneath the bed and the worm-andgearmechanism in the hanger, and Fig. 10 is a broken detail perspective viewof the swinging frame which carries the pad and commode.

The legs 10 of the bedstead terminate at their upper ends inlaterally-extending lugs 11, which lugs are turned up at the end andformed into threaded studs 12, as shown in Fig. 8, and the stud isadapted to be secured by a nut to one of the side pieces of thebedframe. The head-posts and foot-posts 13 are made hollow and areprovided with removable caps 14, which caps serve as nuts and areprovided with threaded sockets, which fit the upper ends of the rods15,which rods extend downward through the posts and are screwed into theupper portions of the legs, as best shownwhich fit upon the rods 15, sothat when the parts are secured together the head-board will be firmlyheld in place. The foot-board is also secured to the foot-posts in thesame manner. The head-board and foot-board are bent inward at theirlower ends, as shown at 18, and are secured to transverse bars 19, whichbars at their outer ends are turned upward, as shown in Fig. 8, and arebolted to the lugs 11 on the upper ends of the legs. The side pieces 20of thebed-frame are also bolted to the lugs by means of the studs 12 andsuitable nuts, and the side pieces are f u rther strengthened by the endstrips 21,Which are riveted to the upper portions of the side strips atthe ends, and these strips 21 are turned up at their inner edges, asshown at 22, and the strips serve to support-the bedspring 23, which isheld in place by means of clamping-bars 24, which bars are placed uponthe ends of the spring and upon the strips 21, and the strips and barsare firmly riveted together.

In constructing the bed the side pieces 20 are preferably made ofangle-iron or of some material made in the shape of angle-iron, as shownin Fig. 4, as when the frame is constructed in this Way it is light andstrong and the various parts may be easily secured to it.

On opposite sides of the bed-frame, near the head of the bed, aredepending cars 25,

which have arms 26 at their lower ends, and

a vertical worm 27 is arranged in one of the ears and is provided with acrank 28, by means of which itmay be turned. The worm meshes with asegmental gear 29 on the end of a shaft 30, and this shaft extendstransversely beneath the bed-frame and turns in the ears 25. The shaft'30 carries a bolsterframe to support the pillows, and the said frame isformed by a bent rod 31, the ends of which are secured to the shaft, andthe bolster-frame is bent so that it will extend diagonally upward andtoward the head-board, as best shown in Fig. 2. The rod 31, forming theframe of the bolster, is provided with longitudinal springbands and withcrossbands33,as shown in Fig. 3, although thecrossbands may be omitted.The bolster-frame affords a convenient support for the pillows, and bymeans of the gear mechanism described it may be adjusted so as to lienearly fiatwise upon the bed, or it may be raised to any desired angle.

The bed spring is cut away in the middle to form a central opening 23,and around this opening is an adjustable frame 34, which is secured tothe edges of the spring, the said frame having its side pieces slottedat the ends, as shown in Fig. 1, so that it may be adjusted to suit thesize of the opening. Extending transversely beneath the bed-spring andnear the ends of the opening are crossbars 35, which are secured to theside pieces of the bed-frame, and these rods are connected at one sideof the opening by a rod 36, which supports a rod 37, one end of thelatter rod being secured to a side of the bed-frame and the other end 38being bent to extend downward, as best shown in Figs. 3 and 1-.

This bent end serves to tilt the commode and pad into a horizontalposition, as hereinafter described. 011 the opposite side of the opening23 and beneath the spring 23 is a 1ongitudinal spring 39, which extendsnearly to the spring 23 and which is supported at its ends by bentU-shaped springs 40, the upper members of said springs being secured tothe main spring 39 and the lower ends being secured to the cross-barsbut the springs 39 and 40 may be made in a single piece, if desired.

A hanger 41 is suspended from the central portion of the main spring 39,and the hanger supports the inner end of a transverse shaft 42, whichextends outward beyond the edge of the bed-frame, and the outer end ofthe rod is mounted in a suitable hanger secured to one of the sidepieces of the frame, as hereinafter described, and is provided with ahandwheel 43, by means of which itmay be turned. The inner end of theshaft 4-2 is threaded, as shown at &4, and meshes with a worm-wheel 45,which is secured to an axle 46, extending through the hanger 4.1, andwhen the shaft is turned the worm-wheel and axle will be also turned.The axle 4:6 projects from each side of the hanger 41 and is provided atone end with a crank 47, which terminates in a laterally-extending stud48, which is adapted to raise the pad, as hereinafter described, and theopposite end of the axle 46 is provided with a similar crank 48, whichterminates at its end in alaterally-extending stud 49, which stud isadapted to raise the commode in the manner described below. The crank 43turns in a stirrup 49, which stirrup is pivoted to the upper portion ofthe hanger 41, as best shown in Figs. 3 and 4, and the opening 50 of thestirrup is nearlycircular,beingslightly elongated vertically, and in thelower extremity of the stirrup is a recess 51, which is adapted toreceive a stud 52 on the crank 48,

and when the stud is in engagement with the recess of the stirrup itwill swing the stirrup until the angle of the stirrup is such that thestud slips from the recess. The lower end of the stirrup is providedwith a pitman 53, which is pivoted to the stirrup, as shown at 54, andthe outer end of the pitman connects by means of a link 55 with a crank56 on the vertical stud 57, which stud is pivoted in the lower bent endof the hanger 5S, and the hanger is secured to one of the side pieces 20of the bed-frame and forms a support for the outer end of the shaft Theupper end of the stud 57 is secured to a frame 59, and the upper portionof this frame is connected by a link 59" with the upper portion of thehanger 58, as best shown in Fig. 10. It will thus be seen that when thepitman 53 is moved back and forth it will actuate the crank 56 and stud57, and thus cause the frame 59 to oscillate horizontally.

Pivoted to one end of the frame 59 is an inwardly-extending arm 60,which is capable of a limited vertical movement and which is adapted tocarry a pad, and a similar arm 61 is pivoted to the opposite side of theframe and is adapted to support a commode. The two arms are connected bya spiral spring 02, the ends of which are secured to depending links 63on the arms and 61, and it will thus be seen that when one arm is inposition beneath the bed and the other is swung outward the tendency ofthe spring will be to pull the outer arm inward, as the inward movementof the arms is limited. The arm 60 is provided on its upper side with astud 6i, which,when the arm is raised, strikes the main spring 39 andprevents the arm from being lifted too high, and on the under side ofthe arm is a hook 65, which is engaged by the stud 48 on the end of thecrank 47,. and the movement of the stud operating on the hook serves topull the hook and arm down or to raise the hook and arm, according tothe direction in which the crank is turned. The inner end of thearm 6Oterminates in a fiat and nearly horizontal portion 66, which forms asupport for the pad-frame 60, and this frame is of open-work and carriesa pad 70, which is usually held in the opening 23 of the bed-spring 23,and thus closes the opening. Vhen the pad is in this position, thespring will be perfectly level and may be used. as an ordinary spring. Abent arm 67 IIO is pivoted at its elbow in the outerend of the arm 60,the upper member of the bent arm being secured to the pad-frame 6D andthe lower end being bent at an angle, as shown at 68, so that when thepad is raised it will strike the bent end 33 of the rod 37, and thiswill tilt the arm and raise one side of the padframe, so as to hold thepad in a perfectly horizontal position, and it will thus be held in aflexible manner, so that it will be as easy to lie upon as thebed-spring 23.

The arm 61 is provided near its outer end with adepending stud 71, whichis adapted to strike the frame 59 and limit the downward movement of thearm, with a stud 7 2 on' the upper side, which is adapted to contactwith the main spring 39 and prevent the arm from being raised too high,and with a hook 73, which is adapted to engage the stud 49 on the end ofthe crank 48, and the stud will raise or lower the arm, according to thedirection in which the crank is turned. The free end of the arm 61 hasan elbow-lever 74 pivoted therein, the lower end of the lever being bentat an angle, as shown at 7 5, so that when the arm is raised the bentend of the lever will contact with the bent end 38 of the rod 37 andtilt the lever in the same manner that the arm 67 of the pad is tilted,as hereinbefore described. The upper end of the lever 74 enters a socket76 on one side of the commode 77. The commode 77 is provided with arecess 78 in one side, and extending transversely across this recess isa pin 7 9, which engages a hook 80, which hook is pivoted to the upperportion of the lever 74, and the shank of this hook extends downward'between two studs 82 on the arm 61, and the studs thus limit themovement of the hook. The commode 77 is adapted to be raised into theopening 23. It is provided at one end with a handle 83, by means ofwhich it may be operated, and it is partially covered at the top and atone end, as shown at 84.

The operation of the device is as follows: \Ve will suppose that thecommode 77 is in position in the .central opening of the bedspring 23,as shown in Fig. 3. The handwheel 43 is then turned to the left, thusturning the shaft 42 and the worm-whee145. This will turn the axle 46and the cranks 47 and 48. At the beginning of this movement the crank 48will be in the upper portion of the stirrup 49, as shown in Fig. 3, andthe inner end of the arm 61, which carries the commode, will besupported on the stud 49 of the crank. As the wheel is turned to theleft the crank 48 will descend, and the arm 61 and commode 77 will alsodescend until the crank reaches the lower portion of the stirrup and thestud 52 on the crank drops into the recess 51 at the lower end of thestirrup. The commode will then have descended into the position shown inFig. 4. The continued movement of the wheel and connected parts causesthe stud on the crank to swing the stirrup forward, and the pitman 53,which is secured to the stirrup, oscillates the frame 59 and swings thecommode horizontally to a point adjacent to the edge of the bed, whereit may be conveniently reached. hen the frame is swung, as describedabove, to bring the commode into this position, it also swings the arm60 inward until the arm is above the stud 48 on the crank 47, and if thewheel is still turned in the same direction the crank will be raised,and the stud on the crank, striking against the arm 60, will raise thearm and pad until the pad fills the opening in the bedspring, and aboutthe time the pad reaches the opening the bent end 68 of the arm 67 willengage the bent end 38 of the rod 37, and thus tilt the pad into aperfectly horizontal position. By reversing the movement of thehandwheel 43 this movement is reversed, the stud 48 engages the hook onthe arm 60 and draws the arm downward, and it is obvious that the entirechain ofmovements would be reversed by the reverse turning of the wheeluntil the commode will be again brought back into the opening, and asthe commode reaches the opening the bent end 75 of the lever 74 willengage the bent end 38 of the rod 37 and tilt the rod, so as to raisethe commode into a horizontal position, its upward movement beinglimited by the hook 80, the shank 81 of which will strike against one ofthe studs 82 and check the movement of the hook and commode.

It will be noticed from the foregoing description that the bed will beextremely convenient for use in a sick-room, and it will be seen thatthe frame of the bedstead may be easily taken apart and packed into asmall compass, or the bed-frame may be removed from the head-board andfoot-board and applied to a bedstead of any other form.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In abed of the character described, abedsteadcomprising a series of legs having laterally-extending lugs at the top,which lugs terminate in vertical threaded studs, removable posts adaptedto rest upon the legs, said posts being slotted vertically, screwsextending downward through the posts and into the legs, said screwshaving cap-nuts at their upper ends, transverse boards connecting theposts and entering the slots, said boards having their side edges bentto fit the screws and having their lower edges bent inwardly, andcross-strips secured to the lower edges of the boards and to the lugs onthe legs, substantially as described.
